Creating Platonic Solids


Recommended Posts

The dodecahedron, well, the lower half.

Trick here is to envision the completed object.

The larger pentagon has edge length equal to the cross bar.

The fold angle is where ctr of cross bar meets the projection of the large pentagon.

The cross bars form a pentagon when "folded" up into position (edge length = edge length of the larger pentagon).

I built a Icosahedron. Old school, similar to drafting class about 50 years ago. Use the ARC tool like a compass and bisect angles to establish points in space. To save time I did most t of the surfaces this way and then filled on the blanks with the 3D polygon tool. It's fun but you have to focus and not walk away.
